Alpha-Chloralose (max. 20% beta-anomer) is a chemical compound primarily used as a sedative and for rodent control. It is synthesized through a chemical reaction involving glucose and chloral, creating a substance with unique physiological properties. Its mode of action primarily involves depressing the central nervous system, leading to reduced responsiveness and hypothermia in targeted organisms. Alpha-Chloralose induces symptoms that facilitate its application as a tranquilizer, particularly in small mammals and birds during scientific research. Additionally, due to its efficacy in lowering metabolic rates, it is utilized as a rodenticide. Within this context, it serves to humanely control rodent populations by inducing hypothermic conditions, leading to a humane death. Its dual functionality—both as a sedative and a rodenticide—makes it a versatile tool in scientific research and pest management. The specification of a maximum 20% beta-anomer content ensures a standardized formulation, enhancing its reliability and consistency for experimental and practical applications.

A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Ascophyllum nodosum, Alaria and Macrocystis pyrifyra (illustrated) and has been shown to have anticoagulant activity. The main constituents are α-1,4 and α-1,2 linked L-fucose sulphates, although galactose also occurs and there are many variations of the basic structure found in different species of Phaeophyta.
The fucose content of this fucan is approx. 31% and it also contains galactose (approx. 2.2%), uronic acid (approx. 12.4%) and sulfate (approx. 32.5%).

Methyl cellulose is a water-soluble polymer that is used as a binder or thickener in pharmaceutical, food, and ceramic processing applications. Methylcellulose has an unusual lower critical solution temperature (LCST) between 40 °C and 50 °C. At temperatures below the LCST it is readily soluble in water; above the LCST it is not soluble, which has a paradoxical effect that heating a saturated solution of methylcellulose will turn it solid, because methylcellulose will precipitate out. The temperature at which this occurs depends on DS-value, with higher DS-values giving lower solubility and lower precipitation temperatures because the polar hydroxyl groups are masked.

2-C-Hydroxymethyl-D-ribose is a sugar that has been found in the cell wall of Mycobacterium tuberculosis. It is also found in some other bacteria, such as Streptomyces coelicolor. 2-C-Hydroxymethyl-D-ribose may be involved in the synthesis of glycan and may have a role in the molybdenum cofactor biosynthesis pathway. This molecule has been shown to have acidic properties, which are most likely due to its hydroxyl groups. The 13C NMR spectrum for this compound shows three peaks at δ H = 138.2, 144.3, and 154.5 ppm corresponding to the ribofuranoside moiety. The skeleton of this molecule was rationalized by attaching an acetaldehyde group to the 2'-hydroxyl group on position C2 of ribose, which is consistent with the observed 13C NMR spectrum. This molecule has

Curdlan is a microbial polysaccharide produced by a mutant strain of Alcaligenes faecalis var. myxogenes which was first shown to produce succinoglucan prior to mutation. Curdlan is a β-1,3 glucan forming clear solutions at about 55 °C which then gels (“low-set”) when cooled. Suspensions of curdlan at higher temperatures form firm resilient gels (“high set”) that melt at 140 - 160 °C.

Isolated from the partial acid and enzymic hydrolysates of several of the mannans,  galactomannans and glucomannans. While the trisaccharide has been isolated from all of these sources the tetrasaccharide has only been isolated from ivory-nut mannan, white spruce (Picea glauca) and Pinus strobus glucomannans. Crystalline penta- and hexa-saccharides have been isolated from ivory-nut mannan hydrolysates.
